Touch Operating Panel HZS 774
The HZS 774 is an intelligent terminal for programming and visualization of automated
processes. Process diagnostics as well as operating and monitoring automated procedures
are simplified using this terminal.
A resistive touch screen serves as the input medium for process data and parameters. The
output is shown on a 7" WVGA TFT color display.
With the LSE mask editor, graphics can be created on the PC, then stored and displayed
on the terminal.
The available interfaces can be used to exchange process data or configure the build-in
terminal. In the internal Flash memory, the operating system, application and application
data are stored.

X10: USB Host 2.0 (Type A)
It should be noted that many of the USB devices on the market do not comply with
USB specifications; this can lead to device malfunctions. It is also possible that
these devices will not be detected at the USB port or function correctly. Therefore, it
is recommended that every USB stick be tested before actual use.
Il faut souligner que la plupart des périphériques USB sur le marché ne sont pas
conformes aux spécifications USB, ce qui peut entraîner des dysfonctionnements de
l'appareil. Il est également possible que ces dispositifs ne seront pas détectés par le
port USB ou qu’ils ne fonctionnent pas correctement. Par conséquent, il est recom-
mandé que chaque clé USB soit testée avant l'utilisation sur l’automate.

n.c. = do not use
Problems can arise if a control is connected to an IP network, which contains mod-
ules that do not have a SIGMATEK operating system. With such devices, Ethernet
packets could be sent to the control with such a high frequency (i.e. broadcasts), that
the high interrupt load could cause a real-time runtime error or runtime error. By
configuring the packet filter (Firewall or Router) accordingly however, it is possible
to connect a network with SIGMATEK hardware to a third-party network without trig-
gering the problems mentioned above.

Des problèmes peuvent survenir si un automate est connecté à un réseau IP con-
tenant des modules qui ne fonctionnent pas sous un système d'exploitation SIG-
MATEK. Avec de tels dispositifs, les paquets Ethernet peuvent être envoyés à
l’automate avec une fréquence tellement élevée (càd. diffusion), que les interruptions
ainsi générées peuvent provoquer une erreur d'exécution. En configurant d’une fa-
çon appropriée le filtre de paquets (pare-feu ou un routeur) il est toutefois possible
de connecter un réseau avec le matériel SIGMATEK à un réseau tiers sans déclench-
er l'erreur mentionnée ci-dessus.

X7: microSD Card
It is recommended that only storage media provided by SIGMATEK
(CompactFlash cards, microSD cards etc.) be used.
Order number for 512 Mbyte EDGE2: 12-630-055
The number of read and write actions have a significant influence on the
lifespan of the storage media.
Il est recommandé de n’utiliser que les supports de stockage approuvés par SIG-
MATEK (compact flash, microSD, etc.).
Numéro de commande pour la carte microSD 512 Mo Edge2 est le: 12-630-055
Le nombre de cycles de lecture et d'écriture a l’influence notable sur la durée de vie
des supports de stockage.
The µSD card is, in this case, not used as an exchangeable storage medium and
therefore should not be removed from the holder.

4 Cooling
The terminal's power loss can reach up to 16.5 Watts. To ensure the necessary air circula-
tion for cooling, the following mounting instructions must be followed!
5 Mounting Instructions
The following distance from the housing should be maintained:
-Left, right, below, above 2 cm
-Rear, 10 cm

6 Buffer Battery
The exchangeable buffer battery ensures that the clock time (RTC) and SRAM data of the
HZS 774 are preserved in the absence of a supply voltage. A lithium battery is installed at
the manufacturer.
After delivery of the HZS 774 and storage of one year, the lifespan of the battery reaches
10 years, if it can be assumed that the module is continually in operation (connected to
supply voltage).
We recommend however, that the battery be replaced every 8 years to ensure optimal
performance.
CAUTION: If the module is not powered for a period of 2 years, the battery is emptied.
Battery order number: 01-690-055
Company
Data
Lithium battery CR2032
RENATA
3.0 V/235 mAh
Use batteries from RENATA with the label CR2032 only!
WARNING! Incorrect use of the batteries could result in fire or explosion! Do not re-
charge, disassemble or throw batteries in fire!
Utilisez seulement des piles de RENATA CR2032!
ATTENTION! La pile peut exploser si elle n’est pas manipulée correctement! Ne pas
recharger, démonter ou jeter au feu!
If the battery voltage is located between both thresholds of the monitoring switch, the bat-
tery can be detected as good during operation, but as low after turning off and on. If this is
the case, it is recommended that the battery be replaced.

6.1 Exchanging the Battery: 1. Option
1. Connect power supply
2. Using the correct Torx
screwdriver, loosen and remove
the battery cover.
When exchanging the battery, caution must be taken to avoid a short circuit. Other-
wise, a defect can be caused in the terminal!
3. Using the strap, remove the
battery from the holder.
4. Insert the new battery with the correct polarity (plus side facing the back of the terminal)
and remount the battery cover.
